Chemical Name: 2-Phenylethanol
Synonyms: Phenylethyl alcohol, β-Phenylethyl alcohol
Chemical Formula: C8H10O
Appearance: Clear, colorless liquid with a pleasant, floral odor
Common Uses: Fragrance in perfumes and soaps, solvent in pharmaceuticals and cosmetics, flavoring agent in food products
CAS Number: 60-12-8
Odor Threshold: Detected by humans at low concentrations, owing to its rose-like smell
Health Hazards: Irritation to eyes, skin, or respiratory system, particularly on prolonged or repeated exposure; possible effects include redness, discomfort, or coughing
Flammability: Classified as combustible rather than highly flammable, so it ignites under high temperatures or strong ignition sources
Signal Words: Often labeled as "Warning" based on hazard assessments
Precautionary Recommendations: Avoid direct contact with eyes and prolonged skin exposure; use only in well-ventilated areas
Main Component: 2-Phenylethanol—typically high purity in industrial applications
Impurities: Trace organic byproducts from synthesis, usually minimal due to refined processing
Physical Form: Liquid at room temperature
Inhalation: Move to fresh air; seek medical attention if symptoms like dizziness or difficulty breathing occur
Skin Contact: Wash area with plenty of soap and water; remove contaminated clothing
Eye Contact: Rinse cautiously with water for several minutes; consult medical advice if irritation persists
Ingestion: Rinse mouth with water; never force vomiting unless instructed by medical professionals
Suitable Extinguishing Media: Foam, dry chemical, or carbon dioxide for small fires; water spray for larger volumes
Special Hazards: May release carbon oxides under combustion
Protective Equipment: Firefighters need self-contained breathing apparatus and full protective gear in confined spaces
Personal Precautions: Avoid breathing vapors; ventilate area; wear suitable gloves and goggles
Environmental Precautions: Prevent spill from entering drains, soil, or waterways
Clean-Up Methods: Use inert absorbents such as sand; place contaminated material in suitable sealed containers for disposal
Safe Handling: Work in areas with adequate ventilation; keep containers sealed when not in use; avoid contact with eyes and skin
Storage Requirements: Store in dry, cool, well-ventilated areas, away from sources of heat or ignition; keep away from incompatible substances such as strong oxidizing agents
Container Materials: Use glass, stainless steel, or compatible plastics to prevent reaction or leaching
Engineering Controls: Use exhaust ventilation to control airborne concentrations
Personal Protection: Wear chemical-resistant gloves, protective goggles, and lab coats
Respiratory Protection: Mask or respirator when handling large volumes or where exposure limits are exceeded
Hygiene Measures: Wash hands and face thoroughly after handling and before eating or drinking
Molecular Weight: Approximately 122.16 g/mol
Boiling Point: Around 219°C
Melting Point: Near -27°C
Density: About 1.02 g/cm³ at 20°C
Solubility: Soluble in alcohol and ether, slightly soluble in water
Vapor Pressure: Low at room temperature
Flash Point: Typically around 102°C (closed cup method)
Chemical Stability: Stable under recommended storage conditions
Conditions to Avoid: High temperatures, ignition sources, strong light
Incompatible Materials: Strong acids, strong oxidizers
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide in case of fire or decomposition
Routes of Exposure: Skin, eyes, inhalation, ingestion
Acute Effects: Minor irritation to skin and eyes at higher concentrations or with poor ventilation
Chronic Effects: Low toxicity based on available studies; not classified as a carcinogen or mutagen
LD50 (Oral, Rat): Published studies report doses above 1000 mg/kg generally tolerated, significant toxicity appears only at very high exposures
Aquatic Toxicity: Limited data suggest low to moderate toxicity to aquatic organisms, breakdown occurs over time
Persistence and Degradability: Readily biodegradable under aerobic conditions, less harmful over extended periods
Bioaccumulation: Unlikely due to low octanol-water partition coefficient
Waste Treatment: Dispose of according to local, regional, and national rules; incineration preferred if feasible
Container Disposal: Triple rinse containers before recycling or disposal; avoid release into environment
Precautions: Do not pour down sink or drains unless allowed by regulatory authorities, due to potential aquatic impact
UN Number: Not classified as a dangerous good for most forms of ground, sea, or air transport, under typical concentrations and volumes
Shipping Precautions: Prevent leakage, use proper labeling and secure packaging
Handling During Transit: Maintain containers upright and protected from physical damage
Global Inventories: Listed in most major chemical inventories, such as TSCA (United States), EINECS (Europe), DSL (Canada)
Labeling: Regulated for hazard communication; safety data required in workplaces owing to risk of mild irritation
Special Limits: Subject to workplace exposure limits and environmental disposal regulations in many regions; requires compliance audit in sensitive environments
